Vlt. should, htnvever7 be noted that this gearing comprises atransverse shaft o mounted on the movable cutter frame and provided at.its ends with pinions p which mesh with the acks .y secured to the mainframe. Two sets ot' gearing are provided for connecting the shaft a'.with the motor, one set fr serving to drive the shaft in one directionto feed the motor .trame forward, and the other set r serving to drivethe shaft in the opposite direction to move the cutter frame backward.By means of a clutch s the shaft 0 can be connected with either sst ofgearing or can be entirely disconnected from both.

Mount-..1 upon the mining' machine and connected with the motor thereofso as to he rotated is a sprocket wheel t which is in alinementlongitudinally with the sprocket wheel e on the truck trame; a chain uis provided which can be placed over these two sprocket wheels toconnect them for the transniission of power when the. mining machine isin place on the truck. When the mining machine is to be removed from thetruck the chain is taken ott'.

The cable reel mechanism (l comprises a trucl 1 which consists ot thewheels 2, axles 3, 3, and frame 4 mounted on the wheels in the usualmanner. have shown the truck as having t'our wheels, but it will beunderstood that the invention is not limited as concerns the number ot`wheels. The reel 5 is rigidly mounted upon the shaft i3 which. isjournaled in the bearings T and 8, supported by standards i) and 1),respectively. These standards are bolted to the track trame and in thismanner the reel is supported with its axis horizontally arranged andtransversely of the machine.

The bearing 7 is movable vertically in the ways 11 t'ormed in thestandard 9, and this vertical movement is accon'iplished by means l sidewalls 1l, 1t of the standard.

of the lever 1L) which pivoted at 13 to the This lever has a short armextending from thel fulcrum point at 13 in onder the bearing T, and along arm extending inthe opposite direction adapted to be grasped by theoperator. This longer arm is `guided between the two bars ot thestandard 14, and can be locked in a lower or upper position ofadjustifient by means of the pin lo which engages with apertures in thebars ot the standard.

The other bearing 8 is cylindriforin with its axis perpendicular to andintersecting the aixis of the shaft 6; and its cylindrical outer tace issocketed within the correspondingly curved block or standard 10. ln thismanner the bearing 8 can accommodate disengaged Jfrom the end 'tace ot'the bearing 7. When the lever 1s 1n its lower position,

its short arm is supporting the bearing 7 and the shaft 6, and the'friction wheel is elevated above and out of contact with the wheels 2.

The reel consists of the metallic end plates 1G and 1T and thewoodenvdrum secured between the plates, the plates being of greaterdiameter than the drum, and consequently, extending radially outwardbeyond the drum so as to provide lateral retaining walls for the cable.18. The end plate 1G is ot' a simple. disk-like form with a central huh19 keyed to the shaft 6. The other end plate 17 consists ot' the hub 20,the annular plate 21 disposed in a vertical plane' relatively nearer theadjacent bearing 8 than is thchub' 2t), and the, connecting walls Q2,the end plate being dish-shaped in its central parts with a surrounding`circular flange.

The cable 18 is secured at its inner end by one or more clamps 23 to thedrum exterior, and passes through the aperture 2l to the chamber withinthe drum, and there branches. One part 25 passing through the gas-tightpacking' box ft' in the wall Q2 and issecured at its end to thecollector rino` 27 mounted upon the wooden insulating sleeve 2.8 whichis rigidly mounted upon the shaft fi. The other branch 29 o the cablelikewise passes through a packing box 3() in another part of the wall 22and is secured at its inner end to a second collector ring,- 31 which isalso mounted upon the sleeve. 28. The sleeve is held in positionlongitudinally by means of the ring 32 which is pinned to the shaft (3between the sleeve 2S andthe bearing 8, and is also held aga-instrotation relatively to the shat't by teeth or other projections in theinner edge ot' the ring I The current collecting mechanism is locatedentirely within thel gas-tight cylindri- :al chamber 233 which isbounded at one end by the dish-like part ot the end plate 17, and at theother end by the cylindrical shield 34 which is bolted at its inner endto the 'end plate 17, and at its outer end is flanged centrally andmachined to lit a eircular shoulder upon the bearing piece 8. Thisgas-tight chamber is in part located within the end plane otl the drumand in part projects beyond thisend plane.

The bearing 8' is formed with two integral inward extending arms 35, 35,disposed ela-dh@ connected Wsh tl 'and preferha;
